Halloween will be here before we know it, so to celebrate I’ve put together a collection of my Top 10 Science Experiments for Halloween. There’s a spooky lava lamp, creepy shadow puppets, fizzy witch and wizard potions and even a noise making machine!
Print off the list below and tick each science activity off as you go along. Which will you try first?
Top 10 Science Activities for Halloween
1. Spooky Lava Lamp
Lave lamps also feature in my Top 10 Science Experiments Every Child Should Try at Least Once. They are super easy to set up and can be used over and over again.
These pumpkin lava lamps always make me smile and would be great for an unusual window decoration this year!
2. Creepy Shadow Puppets
These shadow puppets are another very easy activity and can be made fun for older children by adding coloured cellophane for extra effect.
3. Witchy Potions
This collection of fizzy and slimy potions are great for this time of year and perfect for little witches and wizards. Who doesn’t love a fizzy potion?
4. Scary Giant Sweets
Place leftover Halloween candy jelly sweets in clean water and watch them expand over a few hours as they absorb the water.
5. Bug Filled Ice
Ice excavations are easy and inexpensive to set up. Younger children usually enjoy dripping warm water over the top to melt the ice while older children can try adding salt ( take care, this can make the ice extra cold ) and investigate how the salt speeds up the melting process.
7. Erupting Pumpkins
You’ve probably made an erupting volcano before, but a pumpkin ( once you’ve scooped out the delicious insides ) can be erupted too!
8. Ghostly Optical Illusions
These are actually pumpkin illusions but a ghost would look great too!
9. Nasty Noise Maker
All you need to make spooky noises is a plastic cup, ribbon and a paperclip!
10. Magic Mirror Writing
Write creepy messages backwards using a mirror to help!
Which of my Top 10 Science Experiments for Halloween is your favourite!
